My 2.7 fridge is not cooling enough and I have added more fans. I am thinking about adding another fridge to the other end. We went around the box with a laser temp gauge and fixed anything that looked like an issue. Next week I will be using a friends thermal camera to do the same. I am out of options and need to have the bar completed. Only other thing I can think of is taking a saws all to it and buying a kegerator.
